Thermador Range vent hood turns off by itself
When your Thermador range vent hood turns off by itself, restricted airflow is the most likely cause. Start by checking the range hood filters. Grease and debris can clog the filters, make the blower work harder, and cause the motor to overheat and shut off. Next, inspect the wall vent cap and duct for an obstruction, such as a bird's nest or heavy buildup. With the hood running, check for strong airflow at the inlet and outside outlet. If the venting is clear and the hood still stops, the blower wheel and housing may be binding or the fan blade may not turn freely. A worn exhaust fan motor, fan motor, or blower motor can also shut down after running for a while, even when it still has power. Check the blade for restricted movement, but disconnect power before inspecting or replacing parts. Depending on your Thermador model, the correct repair may require a replacement filter, blower wheel and housing, exhaust fan motor, fan motor, or blower motor. Enter your model number to find the exact replacement part for your Thermador range vent hood.
01 - Thermador Range Vent Hood Filter
The filters in the range hood need to be clean to have good air flow. If the filters are clogged the blower will have a hard time moving air, causing the motor to overheat, and shut off. Inspect the filters and clean or replace them if necessary.

02 - Thermador Range Vent Hood Wall Vent Cap for 6 Inch Duct
If the vent hood motor keeps shutting off the venting may be obstructed. If accessible, check the outside vent cap for a bird's nest, etc. Turn the vent hood on and check for good air flow at the inlet and outlet. If you suspect the vent is clogged, but you cannot access it, you should have someone check it for you.

03 - Thermador Range Vent Hood Blower Wheel and Housing
The blower has a motor that can overheat and shut off. If the motor is not turning freely, or is running for awhile and shutting off, but still has power to it, the blower will need to be replaced.
Highly Likely
04 - Thermador Range Vent Hood Exhaust Fan Motor
If the exhaust fan motor has power to it but keeps shutting off, the windings or bearings may be bad. Try turning the fan blade by hand. If the fan blade does not turn freely, or the motor keeps shutting off when it has power to it, the exhaust fan motor will need to be replaced.
Highly Likely
05 - Thermador Range Vent Hood Fan Motor
If the fan motor has power to it but keeps shutting off, the windings or bearings may be bad. Try turning the fan blade by hand. If the fan blade does not turn freely, or the motor keeps shutting off when it has power to it, the fan motor will need to be replaced.
Highly Likely
06 - Thermador Range Vent Hood Blower Motor
If the blower motor windings or bearings are bad the motor may overheat and shut off. Make sure the blower wheel turns freely. If the motor doesn’t turn freely, or the motor is shutting off after it runs awhile, the motor may be bad and will need to be replaced.
Highly Likely
